Características físicas, mecánicas e hidráulicas evaluadas en el pavimento flexible de la vía San Andrés – Guano

Climate conditions, particularly heavy rains, are factors that compromise the stability and durability of flexible pavements. In Andean areas like Ecuador, humidity is another factor that aggravates road infrastructure. Therefore, knowing the physical, mechanical, and hydraulic properties is key to preventing premature damage. This research is conducted on the San Andrés Guano Road, employing a quantitative descriptive methodology. It was determined that the base layer, classified as Class 4 poorly graded sand, has a moderate degree of compaction, with an average value of 85.08% and a low CBR of 45.56%. The subgrade, composed of poorly graded fine sand, indicates a low bearing capacity, with an average CBR of 19.85%. Both values are below the minimums established by the MOP regulations (2002). The asphalt layer exhibited a medium degree of compaction, with a value of 95.23%; these values are below the ranges specified by the regulations. The determined runoff coefficient falls within a range of 97%; however, compared to the IEOS (1992) regulations, which propose a range of 85% to 90%, it is notably lower than the established value. The correlation indicated a weak relationship between the properties described in the research, suggesting that other factors may be directly involved in the runoff coefficient. These results underscore the importance of enhancing material control and compaction during construction to ensure adequate drainage during precipitation.
